- Replacing the usual principle of conservation of numbers with the equivalent principle of continuity of flow (or rates) leads to a very heuristic approach to modeling time lags in populations. The approach allows the direct use of unequal time lags (or age classes of unequal lengths) without the implicit assumption of a stable age distribution. Furthermore, for simple, linear natality processes, it allows direct estimation of the biotic potential and of the frequencies of inherent oscillations.
